Abstract
A sample for use in determining strain, the sample comprising: a substrate, whereinthe external surface of the substrate is partially, or fully, coated in a conductive toform a transmission line, the coated substrate being configured to be connected toelectronic equipment such that the strain on the sample is determinable by applyingand measuring a signal to the coated substrate using the electronic equipment. The samplemay be a geogrid rib. The substrate may comprise a geosynthetic. A strain sensor maycomprise the sample. Another aspect is a method of measuring strain through a sample using a sweep offrequencies into the transmission line and measuring the phase of the signal at each frequency.
